40 Gbit/s 'drop and insert' multiplexing with novel clock recovery using an electroabsorption modulator in a bi-directional configuration

40 Gbit/s 'drop and insert' multiplexing is demonstrated using electroabsorption modulator optical TDM multiplexers, and analysed using BER measurements. A novel method of clock recovery is presented, which exhibits ultra-low jitter and uses low-speed control electronics.
